the stack space, then the program runs the stack space about how much, and what factors, can not be estimated?4. What is the limit of the amount of RAM used in monolithic microcomputer? (refers to Keil compiled data value should not be more than how much)A: How the RAM space is allocated when the program is running in a single-chip microcomputer1, the allocation of RAM is related to the compilation mode you choose, you can look at the compiler's manu

unit that accelerates multimedia and signal processing algorithms. Neno technology includes single instruction multi-data smid instructions and vector floating-point VFPv3 instructions, so the compiler needs to support the SMID instruction set and the VFPV3 instruction set in order to achieve optimal performance of the kernel.2.2. Compiling toolsArm development from the source code to the final generation of the executable binaries need to rely on a system of development tools, such as C compil

Cortex Microcontroller Software Interface standards (CORTEX microcontroller software Interface Standard, CMSIS) with kernel support, optimized DSP algorithm library, As well as a reference to the implementation of RTOS kernel for real-time operating system running on the CORTEX-M7 processor. Cmsis-pack can ensure rapid access to a wide range of tools through the integration of software components,

Originally, it was uncomfortable for Xiao Zhu to switch the developed hardware platform when he was a little familiar with the 80C51 series. Discard familiar tools such as Keil and serial download tool to get familiar with new tools. Xiao Zhu started the mix project with such emotions. T

Install keiluvision4to register keil_lic.exe 1. First of all, download the EXE executable file of keil uVision4 on the Internet. There may be two versions: 51-core single-chip microcomputer (33.3 M) and microcontroller Development (244 M ), you can choose based on your actual needs. 2. Follow the steps to install keil uVision4 Note: The following two points ar

In the previous blog post, we have learned how to coordinate how each level in the whole system works, and the command issued by the application layer reaches the drive layer under the kernel, thus achieving the purpose of operating the hardware layer.Let's look at the code in the final molded "shell driver" first_drv.c in the last blog post:#include As I said in my previous blog post, there is a disadvantage to this driver, and we'll optimize it in the next post. Now first to compile the driver

run the C program environment, such as the stack pointer SP does not point to the correct location. Assembly code should complete the original hardware device initialization, and prepare the C run environment, so that the function can be written in C language.------Solution--------------------------------------------------------1. C language does not have the SP (Stack Pointer Register), CPSR, CP15 and other control instructions, to initialize these, must use Assembly code, the other parts are

OverviewThis design uses the FPGA technology, realizes the 8051 monolithic microcomputer soft core in the FPGA, the external SPI Flash code data loads into the FPGA internal RAM, then resets the MC8051, realizes the external flash startup MC8051.2. System Block Diagram8051 uses Oregano Systems Inc. open source MC8051 soft core. SPI Flash uses the W25Q16 chip to store 8051 of code programs.

will be uncertain. When the total number of variables exceeds 128 bytes, you must reset the storage mode in the compiler. There are three storage modes: small, compact, and large, you can select options in the Keil compiler, as shown in table 4.4.1. It determines the default storage region where data such as variables and function parameters of the storage type are not explicitly specified. If you need to use a non-default storage mode in some functi

MSC1210 can be used as both Flash program memory and data Flash program. Because it takes some space to embed the real-time operating system and network protocol, it is used as the program memory, and 74hc573 is used as the address lock, and 6264 is extended as the external data storage, the 8 KB data storage space is sufficient for the program to run normally. Figure 3 shows the hardware connection between MSC1210 and data storage. 2.1.3 GPRS wireless data transmission module As the wireless t

the root file system.3. windows can recognize drive C and drive D, so it will certainly be able to read and write the drive. This involves something called a driver. Of course, it's not just hard disks, but also NICs and USB. Embedded Linux can read and execute applications from Flash. It must also have Flash drivers, not just Flash.Let's talk about it first. Embedded LINUX contains four major parts: bootloader, kernel, driver, and root file system.I. bootloader:It is a slightly complicated bar
